INTRODUCTION
Ovention MiSA™ Microwave Speed-Assist Ovens set a new
standard in cooking quality, speed, flexibility, and efficiency.
A new discovery in air handling not only speeds the cooking
process,but“scrubs”andrecirculatestheairthroughtheoven—
eliminating the need for a hood system in most installations.
Using an icon-driven touchscreen, operators can use, edit, and
develop over 4000 custom recipes. Recipes can be developed
to include up to three cooking stages—each with varying heat
profiles, air velocity settings, timing, and microwave power
percentages.
Ovention MiSA ovens are products of extensive research and
field testing. The materials used were selected for maximum
durability, attractive appearance, and optimum performance.
Every unit is inspected and tested thoroughly prior to shipment.
This manual provides the installation, safety, and operating
instructions for Ovention MiSA ovens. Ovention recommends
all installation, operating, and safety instructions appearing in
this manual be read prior to installation or operation of the oven.

open since open-door operation can result in harmful
exposure to microwave energy. It is important not to
defeat or tamper with the safety interlocks.
• Do not operate the oven if it is damaged. It is particularly
important that the oven door close properly and that
there is no damage to the: (1) Door (bent), (2) hinges
and latches (broken or loosened), (3) door seals and
sealing surfaces.
• Do not place any object between the oven front face and
the door or allow soil or cleaner residue to accumulate
on sealing surfaces.
• The oven should not be adjusted or repaired by anyone
except properly qualified service personnel.
FIRE HAZARD:
• Install witha minimum of1″ (25 mm)of spacefrom
rear of unit to any surface. If safe distances are not
maintained, discoloration or combustion could occur.
• Do not block or cover any cabinet venting.
• Do not use an extension cord. If power cord is too
short, contact a qualified electrician to determine and
install proper voltage and size electrical receptacle
near unit.
• Do not overcook food. Carefully attend to oven if paper,
plastic, or other combustibles items are placed inside
oven to facilitate cooking.
• Remove twist-ties from bags before placing in oven.
IMPORTANT NOTE
If materials inside oven chamber ignite:
• Keep oven door closed.
• Turn OFF power switch.
• Unplug unit/disconnect power at circuit breaker.
EXPLOSION HAZARD: Do not store or use gasoline or
other flammable vapors or liquids in the vicinity of this or
any other appliance.

subject operators of the equipment to hazardous
electrical voltage, resulting in electrical shock or burn.
Genuine Ovention Replacement Parts are specified to
operate safely in the environments in which they are
used. Some after-market or generic replacement parts
do not have the characteristics that will allow them to
operate safely in Ovention equipment.
Liquids such as water, coffee, or tea are able to be
overheated beyond boiling point without appearing to
be boiling. Visible bubbling or boiling when container
is removed from microwave oven is not always present.
THIS COULD RESULT IN VERY HOT LIQUID SUDDENLY
BOILING OVER WHEN CONTAINER IS DISTURBED OR
A UTENSIL IS INSERTED INTO THE LIQUID.

MODEL DESCRIPTION
All Models
Ovention MiSA™ Microwave Speed-Assist Ovens are designed
to provide unequaled speed and flexibility in both kitchen and
front-of-the-house installations. The variety of menu options,
small footprint, low heat escape, and hood-less installation
make the MiSA™ oven a single solution alternative to multiple
pieces of cooking equipment.
MiSA ovens are equipped with two top-mounted microwave
units and a convected air blower. The microwave units provide
precise and powerful, high-speed heating of the food product.
The convected air blower directs heated air throughout the
inside of the oven chamber for traditional, even cooking
and finishing. Microwave heating is adjustable in intensity
and duration; and convected air heating is adjustable in
temperature, intensity, and duration by developing/using
programmed recipes on the touchscreen.
Operator controls for the oven consist of a touchscreen
and a Power I/O (on/off) switch. A USB port allows the
uploading of pre-programmed recipes, installation of software
(1829 mm) cord and plug set is standard.
Any oven and microwave-safe pan can be used in the oven
chamber of the MiSA oven. The oven chamber has a capacity
